that is because you have there a type:18 in your file, that is a shape, but that isn’t supported anymore.
if you remove these pieces
{
formIndex:17400,
lineSize:1,
location:“300,101”,
points:“300,87;300,87”,
shapeType:1,
size:“1,1”,
typeid:18,
uuid:“36124461-F899-41D7-A4B3-98F66A8DF722”
},
{
foreground:“#666666”,
formIndex:20000,
lineSize:1,
location:“6,242”,
points:“880,219;7,219”,
shapeType:1,
size:“873,1”,
typeid:18,
uuid:“9268BBFA-BB0D-46AB-9E85-8D733899A629”
},
{
foreground:“#666666”,
formIndex:20100,
lineSize:1,
location:“6,297”,
points:“880,274;7,274”,
shapeType:1,
size:“873,1”,
typeid:18,
uuid:“CA15705C-6C04-4539-9477-90AAB12BD16B”
},
it should work fine again.
With the fix i already did it wouldn’t bomb out anymore when rendering.
